Donald J. Trump officially became the presidential nominee of the Republican Party on the second day of its convention in Cleveland on Tuesday -- as his children and the Republican leadership took the stage. Here are some of the night's top moments that you might have missed.

Trump Clinches the NominationDonald Trump locked up the Republican Party's presidential nomination on Tuesday just after 7 p.m. when his son, Donald Trump Jr., announced from the floor that the majority of New York's delegates were casting their vote for him.

Washington, D.C.'s delegation tried to award 10 votes to U.S. Sen. Marco Rubio and nine to Kasich in accordance with its primary results, but was turned back by convention officials. All of its votes went to Trump. On MSNBC, one of the Kasich delegates called the rule interpretation an outrage.

Alaska's delegation objected to the same rule by demanding a roll call vote. The request was denied -- and all of its delegates also went to Trump -- but the convention's speakers were delayed.

Auditioning for Attorney General?New Jersey Gov. Chris Christie, a former federal prosecutor, told the audience that because the U.S. Justice Department had refused to prosecute Hillary Clinton, he would present the facts and let them sit as a jury of her peers.

"She fights for the wrong people," he said. "She never fights for us."

He called her the architect of the disastrous overthrow of the Libyan dictator Muammar Gaddafi, an apologist for Nigeria's Boko Haram, which later abducted still-missing school girls, an awful judge of Syria President Bashar al-Assad and the inept negotiator of a nuclear arms deal with Iran, the worst in U.S. history.

"If you think Chris Christie can lecture anyone on ethics, we have a bridge to sell you," she wrote.

“For too long our country has ignored its problems, punting them down the road,” he said. “We need to elect a man who has a track record of accomplishing the impossible.” (Published Tuesday, July 19, 2016)

In addition to Donald Trump Jr.'s role in his father's nomination, he gave what some commentators called the best speech of the convention. He described his father as his mentor and his best friend, a man who never gives up, who changed the skyline of New York City.

"For my father, impossible is just the starting point," he said. "That's how he approaches business projects. That's how he approaches life."

He said his father had spent his career with regular Americans, pouring concrete and hanging sheetrock on construction sites, valuing their opinions as much or more than the graduates of Harvard University or Wharton School of the University of Pennsylvania.

"We didn't learn from MBAs," the son said. "We learned from people who had doctorates in common sense."

Donald Trump's daughter, Tiffany Trump, called her father "a natural born encourager" whose "desire for excellence is contagious."

"He always helped me be the best version of myself by encouragement and by example," she said.

They spoke as fallout continued over Melania Trump's speech Monday night — a portion of which was nearly identical to one Michelle Obama gave in 2008. NBC News reported that the original draft of the speech did not include the disputed section.

The campaign denied there had been any plagiarism in the speech by Donald Trump's wife, and deflected questions about whether anyone should be fired. Paul Manafort, Trump's campaign chairman, accused Hillary Clinton of bringing attention to the accusations. But Donald Trump Jr. seemed to blame unidentified speechwriters and the former campaign manager, Corey Lewandowski, who was pushed out in favor of Manafort, said Manafort should take responsibility.
